Damien Echols has nightmares about being back in Arkansas. As a member of the West Memphis Three, Echols spent nearly two decades on death row in Arkansas — accused of the 1993 murder of three eight-year-old boys — but was later released due to new DNA evidence.

But he is set to return on Friday in protest of the state government's decision to execute seven men in 10 days because their execution drugs are expiring.

The two nights he will spend in Arkansas will be his longest stay and only the second time he has returned since his release in 2011.

"Ever since the executions were announced, I've had tons and tons of people contacting me to, number one, would I help in some way? Number two, would I be willing to come back to Arkansas and speak out against this?" Echols told NBC News.
